Abstract

A process for the production of aluminium in two steps: 2Al2O3+9C=Al4C3+6CO (ii) and Al4C3+Al2O3=6Al+3CO (iii) Reaction (ii) takes place in a materials addition chamber and reaction (iii) in a high temperature chamber. Slag is circulated between the chambers via conduits by the action of gas generated in reaction (iii) in the conduits. Aluminium production in the high temperature chamber and slag circulation rate are independently controllable by the provision of independent heat sources.
